A canonical starting point for new operators. Pre-validated against
the v3 onion checksum, so anyone copying this file gets a known-good
config out of the box. Documents:
* The 7 hardcoded seeds from src/onionseed.h (with port 24112)
* How to add the 7 dynamic seeds from seeds.cryptographic-triangles.org
(commented out, since the daemon fetches them automatically)
* The pre-commit hook installation instructions
* The Tor-only requirement (notor=0 must stay)
* Standard index flags (txindex, addressindex, spentindex, timestampindex)
* dbcache sizing guidance
The 7 hardcoded seeds were taken verbatim from src/onionseed.h and
verified by scripts/validate_onion_seeds.py. The C++ test suite
src/test/onion_v3_tests.cpp also re-validates them at every build.
Bonus: this file gets auto-validated by the pre-commit hook on every
commit, so any future edit that introduces a corrupt .onion will be
caught before it can reach a deployment.
